Xerox said on Wednesday that its scientists have perfected a new method for printing hidden fluorescent wording using standard digital printing equipment.

According to the company, the discovery paves the way for customers and businesses alike to add an additional layer of security to commonly printed materials such as checks, tickets, coupons, and other high-value documents.

The hidden fluorescent words and letters show up only under ultraviolet light, said Reiner Eschbach, a research fellow in the Xerox Innovation Group, and the co-inventor of the patented process. Whats more, the method for printing them doesnt require the use of special fluorescent inks.

“Whats amazes people about the new technology is that we can create fluorescent writing on a digital printer without using fluorescent ink,” said Eschbach in a statement on Wednesday.

“That means a four-color digital printer can print everything it normally would, and it can simultaneously individualize a document with a fluorescent identifier,” he added.
